Canvas 12 User Guide
Make sure when you copy the documents to another disk, that you maintain the original folder
structure. It is a good idea to open the Canvas document that you copied, and check that the links
have not been broken (see "To verify proxy links:" on page 556 for more information).
You can also replace a proxy with its linked image to eliminate the need to copy the image file. To
learn how to do this, see "To replace a proxy with its linked image:" on page 556.
To create a proxy by acquiring a file:
You can use the Import command to create a proxy that is linked to a TIFF, JPEG, or CVI file.
You can edit acquired proxies the same as other proxy images. However, some changes you might
make, such as adding image channels, are not supported by JPEG or TIFF files.
1. To acquire an image from a file, choose Image | Import and choose a file format in the Import
dialog box.
2. In the Import dialog box, select the Acquire As Proxy option. Select the image files to import
and click Import.
3. In the Proxy Info dialog box, type the proxy resolution in the “Make…Times Smaller” box. The
larger the number, the lower the resolution of the proxy image in the document.
4. Click OK. Canvas places the proxy images in the document.
Editing proxies
When you place a proxy object in image-edit mode, Canvas loads and displays the linked image file in
place of the proxy. If the original image has changed, you see the changes.
Changes you make in image-edit mode are saved in the linked image file on disk when you exit image-
edit mode. Canvas then displays an updated proxy.
Editing an image linked to a proxy is the same as editing any image in Canvas; you can use painting
tools and commands to alter pixels in the original image.
